Where to start with the 5.3L?

[Rmitch223]

Just got rid of my favorite short wide bed chevy (2000) for a 09 GMC Sierra 2WD 5.3L. After looking up the vin I found out the engine is a LY5.

My question is where to start on getting more power out of this engine. Currently this truck only has a K&N drop in filter and a Flowmaster cat-back system. Where should I go from here as far as bolt ons or any tuning tips to get more power out of this engine?

My plans are:
Hooker long tube headers & Y pipe with my current flowmaster 40's series muffler, not a big flowmaster fan but if what im going to use now.

Maybe a Hypertech programmer and a MAC Cold Air Intake..

What would you suggest?

Even little things like removing mass air screen or any tips you know of would help...


Thanks alot,

Ryan

Just got off the phone with Nelson Performance and will definitly being going that route with the tune.

Plans for the truck: Drag Racing & DD would like to get into the 13's - high 12's if possible lol

Your truck doesnt have the screen in the maf. NNBS dont have a screen.

Thanks guys, I think the first thing on my list is gonna be the nelson tune, then intake, headers and hopefully a cam to follow.


Sleeper, I may spray it one day but that will be a last resort for me.
